1 High Performance Circuit Breaker S800HV-K for applications up to 1000 V AC The new High Performance Circuit Breaker S800HV is designed for voltages up to 580/1000 V AC. The S800HV is available as 1-, 2- and 3-pole version. The small pole width of only 27 mm allows a space-saving installation. The current range covers the rated operational current range from A with a max. rated short-circuit breaking capacity (Icu) of 4 ka. Due to the high rated operational voltage, the field of application is wide from underground mining to distributions on high altitudes. Features Rated operational voltage 580/1000 V AC Rated short-circuit breaking capacity (Icu) 4 ka at 580/1000 V AC Useable with short-circuit current limiter to increase breaking capacity of 15 ka Fast modification on ring lug terminal is possible Compact and space saving Application Transformer protection Motor protection Mining industry, opencast and underground Power distribution systems e. g. tunnels Lighting systems protection Protection of ventilation equipment Used for application supplied by long wires

5 Increase of breaking capacity For a higher short-circuit breaking capacity, a self-resetting short-circuit limiter, the, can be installed upstream to the S803HV-K. The ultimate short-circuit breaking capacity (Icu) is thus increased to 15 ka. 2CCC413403F0001 The can be used either for line or group protection. Line protection: Each S803HV-K will be protected with one. Group protection: One single can protect several mounted downstream S803HV-K. This case is cost effective as all of the used S803HV-K will have a short-circuit breaking capacity of 15 ka. In case of a failure, only the defective branch will open. The other branches with S803HV-K will remain operative. Back-protection and total selectivity is given due to the use of.
